The prerequisite for on-site dynamic balancing is the determination of unbalance faults, the determination of the number of balance faces and the completion of various preparations, which can ensure time-saving and labor-saving balancing work. If the equipment has been shut down, replace the reflective tape. Check whether the balance instrument function and power supply are sufficient and the cable connection status.

The installation position of the vibration sensor and photoelectric sensor should always remain the same. Each data record must be accurate, and at the same time, compare the vibration amplitude and phase after the first retry with the original record. If the change is not large and does not reach more than 20%, it means that the retry is inappropriate, and its size and phase must be reconsidered. Location.

The installation principle of the trial weight is: the installation is reasonable, the rotor should not be dropped when it is running, and it should be easy to remove at the same time. Calculate the major hours and input the original record, additional trial re-record and trial re-block data into the calculator accurately. After the counterweight is added to the designated position, it must be firm to prevent it from falling during operation.

After entering the work site, be familiar with the surrounding environment and pay special attention to safety issues and fire prevention issues. Before starting the equipment, contact the on-site operator in time, and start the equipment only after confirming that it is correct. During all on-site balancing work, you should always pay attention to and observe the operating status of the equipment. If an abnormal phenomenon is found in the equipment, you should immediately signal the shutdown to protect the personal and equipment safety.
